Operating Principle, Applications, Magnetic Units

Operating Principle


The magneto-optic principle is based on the Faraday effect. It describes the rotation of the plarizaton plane of linearly polarized light when passing through a transparent medium. When light passes through a magneto-optical medium, the different angles of rotation of the polarization depends on the local magnetic field strength, resulting in contrast-differences which can be visually evaluated. Thus, a direct, real-time visualization of a quasi-static magnetic field over the entire sensor surface is achieved.

Applications

Magnetic Ink on Check

Magnetic Units


Conversion of Gauss to Tesla:
1µG = 0.1nT, 1mG = 100nT, 1G = 100µT, 10G = 1mT, 10,000G = 1T


Relationship between Magnetic Flux Density (B) and Magnetic Field Strength (H):
In vacuum (or air) B=µoH. For SI units µo = 4pi x 10-7H/m, B is expressed in Tesla and H in Ampere turn/m or A/m. Hence in vacuum or air a flux density of 1T = 796kA/m.

For cgs units µo = 1, B is expressed in gauss and H in oersted. Hence in vacuum or air a flux density of 1 gauss = 1 oersted.
